Rabbi Elazar ben Azariah says: If there is no Torah, there is no proper conduct. If there is no proper conduct, there is no Torah.  If there is no wisdom, there is no fear [of God]. If there is no fear [of God], there is no wisdom.  If there is no un-derstanding, there is no knowledge. If there is no knowledge, there is no understanding.  If there is no flour, there is no Torah. If there is no Torah, there is no flour.  He used to say: Anyone whose wisdom exceeds his actions, to what is he lik-ened? To a tree whose branches are numerous but whose roots are few, then the wind comes and uproots it and turns it up-side down, as it is stated: He will be like a lone tree in the desert, and will not see when goodness comes; it dwells in parched lands in the wilderness, in a salty, uninhabited land. But one whose actions exceed his wisdom, to what is he likened? To a tree whose branches are few but whose roots are numerous; even if all the winds in the world were to come and blow against it, they could not budge it from its place, as it is stated: He will be like a tree planted near water, which spreads out its roots along a brook and does not see when heat comes, whose foliage is ever fresh; it will not worry in a year of drought and will not stop producing fruit.
